NURSIN -BOTTLE.

Speciflcationot Letters Patent. Pate t d J '29 1 j Application filed January 3, 1920. Serial No. 349,241.

Beit knownthat I, Dr. \VILLIAM EDWARD GODDARD, a citizen of the United States, and

' resident of Watertown, in the county of;

Jefferson and State of Wisconsin, have invented certain new and useful Improvei declare that the followingis a full, clear,

and exact description thereof. n

My invention refers to nursing bottles, one object being to provide a simple, durable nursing bottleformed of pliable rubber or analogous material whereby the body is rendered collapsibleandthe outer crown thickness tothus prevent stoppage of the portion non-collapsible due to variation in flow of milk irrespective of the position which the collapsible portion of the bottle ma assume. a r

i nother object is to provide the body of the bottle with an opening of the full area of said bottle so that it can bereadily turned inside outor reversed whereby the walls may be thoroughly cleansed.

Another object is to provide the upper portions of the bottle'with walls which are slightlythicker in cross sectionftha'n the lower portion ofthe body whereby the lower portion will .thus tend to collapse earlier than the upper portion when the contents of the bottle are gradually being withdrawn and thus facilitate withdrawing the contents freely irrespective of the position that the body of-the bottle may assume.

.. Anotherobject is to provide the nipple,

which is an integralpart of the body with the upper portion or discharge portion thereof, of slightly thicker walls'so that it will not collapse or suck tight.

A further object is .to provide the nipple with a thickened crowned center plug about which one or more openings may be formed whereby the action of the plug when suction is placed thereon would tend to open the suction ducts and close them automatically so asto guard against stoppage of the How when .a suction force is exerted upon the nipple and which construction will also permit positive closure of the discharge ducts-when the suction force is relieved.

Another importantfeature of the invention is that owing to the flexible walls of the body when said body collapses, the resistance at the adjacent outer collapsed edges will form open ducts so that the contents of the bottle although partly collapsed can be freely drawn fromthe bottom of said bottle through the nipple, thus preventing inadvertent cut-off of a portion of'the con tents. In other words a continuous channel is maintained through which the supply can be discharged into the nipple.

further object is to provide the nipple at its base with a weakened portion which in con unction with the thickened portion at its dlscharge endwill' prevent Spurting of the contents when the nippleis closed down by biting to thus obviate any liability of chok- 111g the nursing infant, and it will also permit'the'contents of the nipple to return to the body after such biting upon it.

A still further object is to arrange one or more discharge ducts about the thickened plug portion of the nipple so that they will automatically close when pressure is reliewd from it to prevent the introduction of air through the duct into the body of the bottle. Another primary object of this invention is to provide a simple and effective means for closing the bottom of the bottle by a single clamping element operating in conjunction with end snaps. 1

"With the above and-other minor objects inview, the invention consists in certain peculiarities of structure and combination of parts .as herein set forth with reference to the accompanying drawings and subsequently claimed.

In the drawing: A s

Figure 1 represents a side elevational view of a nursing bottle embodying the features of my invention with the upper part broken away-and in section to more clearly illustrate structural features.

Fig. 2 is a cross section of the same, showing the bottom clamping mechanism, the section being indicated by the line 2-2 of j is arranged to be clamped by suitable means to the upper portion of said body, in this instance the body portion of the bottle obviously is closed, and

Fig. 5 illustrates a detailed plan view upon an enlarged scale of the nipple showing my preferred method of forming the discharge ducts about the plug portion thereof.

Referring by characters to the drawing, 1 represents the cylindrical body portion of the bottle and 2 the upper portion thereof when the walls are collapsed adjacent to the opening, the edges thereof will flush as shown at 3 in Fig. 3. The bottom opening is closed by pressing the wallsitogether and fitting thereto a spring metal U-shaped clamp 4 having side strips that are normally folded to .form .a contracted throat at their upper edges so as to securely, pinch the-rubber walls together. At the open ends ofthe.

clamp there are riveted or otherwise secured hinged snap pieces 5 which are U-shaped in cross section and adapted. to be swung out wardly when the clamp is removed and to be folded back upon the side walls ofthe clamp when-it is afliXedtothebottlebody as shown in Fig. 1, :thus positively pinching the side walls of said clamp into'engagement with the wallsof the body to prevent leakage. This clamping mechanism, it will be observed, has no projections which would be liable to-catch into thecovering or-otherwise injure'in any way the'infant should the bottle be carelessly handled, the structure :a a whole being-readily connected .and disconnected and also capable of being cleaned readily was to render the device as a whole positively sanitary.

As shown in Fig. 1, the upper thickened portion 2 of the bottle :body merges into a nipple 6 having a weakened base portion 7 and a thickened dischargeend 8. Theudischarge end in turn is .formed with .a thick ened crowned plug 9 about the edges of which there are formed one-or more milk ducts 10 which are preferably narrow .incisions grouped about the plug and discharging radially. The drawin illustrates the incisions of slightly magnified dimensions but it is understoodthat when the nipple is not subjected to force these incisions are closed by the normal expansile tendency-of the rubber. lVhenpressme is put upon the nipple the suction or draft upon the thickened :plugtends to vibrate it slightly, to thus open the ducts whereby the contents of @the bottle can be freely withdrawn therefrom, and it follows :that when this force is re lieved, the plug, acting like a valve, will close the ducts. It will also be observedthat by clamping the side walls of the bottle body together, there will be formed air ducts which will lead from the bottom to the top portion of the bottle and thus permit the athermore, owingto the delicate ifiexi ilityof :the body "walls :and their variation .in thickthroughout whereby it can :readily re- ;enedportion 2, the :thickened'portion 2 and ,be ilimited to structural ifeatures except :so

flexible .material, :a -cyl1ndrical body .portion toward the apex and a anipp'le :extending contents of the bottle-to be drawn out irrespective of the position of it, and even ,though the bottle is=flattened materially, this result will attain :to preventzcloggi F urness, whenrthe contents of the bottle'is withdrawn, the walls will collapse .and thus prevent a vacuum being formed back of said contents, which under ordinary QCOIldltlODS would result and givesmore or less stoppage of :a uniformflow.

I also wish tocall attention :to the '.;fact r that :owing to ,the thickened end vof the *n'ipple and its weakened base, said nipple "will 8.0

function to prevent total collapse or Lfiooding when =the infant bites :upon'the *walls of said nipple. The ibody vand nipplecan be readily cleansed b. simply turning the wentire structure insi' e out -w'hereby said "walls can-be scrubbed to insure ;p.erfect anitation,

this being partly due :to *theifact that the filling opening of :the bottle is approximately of the same diameter as .the body 1m I versed. Fig. iaillustrates-a modified :form

a of my invention wherein %the bottom l of the body portion is closed a and the filling opening is in uxtaposition ito the upperithickbody portion 1- in this instance are formed with companionbeadszl'l'and l2irespectively which are secured by suitable metallic clamping rings 13, thesamfibeing'dmwn :to- ,gether byua collar 14 which :is i-in [threaded 1 union -with the rings. Thisuconstruction however in 1 detail iforms (no part of :my in vention and is simply illustrated to show; one method of attaching the body ortion' of the bottle to the upper reinforce topper- 1 tion :thereof.

It will also be understood athat while '1 have shown and described tone mpecific iozm of my invention in detail, I do :not wish to {far :as they are called for 1 in athe claims.

, Iclaim:

.1. .As a.newarticle@ofmanufacturea one :piece collapsible nursingbottle formed from 11b and a crowned top .portion, the walls a of I the &body portion being of iless thicknesslthan the walls .of the crowned top :portion, which walls are gradually increased :in thickness :fromnthe crowned apex, "the base walls .of which vare gradually areduced in thickness with relation to :the crowned apex Band ithe upper end to). the :Iiipple walls being ggraduallygincreased in thickness to resist collapse, and means for :flattening and closing the lower end of the body portion.

2. Asanew articleof-manufactureaione ,piece collapsible nursingibottle formed from flexible material 'havingan open bottomcy lindrical body and a crowned top merging "into a nipple, the Walls of the body portion being of less thickness than the Walls of the crowned portion and the Walls of the nipple being proportionately of less thickness at the base than at the top portion thereof to thereby resist total collapse While permitting fiexure at its base, and; meens for flattening and closing the open bottom of the body portion,

In testimony that I claim the foregoing I cousin,

DR. GODDARD.
